What camshaft would you use in a stock 265? Most parts houses list only an anemic .333” lift hydraulic cam for the 265 engine. This was the “low lift” short duration cam installed in the base 162 hp 265. This cam has the flat in the rear journal for the unique 265 lifter oiling. The Power Pack 265’s, as well as the 2 bbl engines with Powerglide transmissions, were equipped with a higher lift (.373”) and longer duration cam. I don’t believe anyone makes a replacement for the 1956 Power Pack camshaft. I am thinking of using the common GM #3896929 cam in my 265. This is the stock hydraulic cam used in most SBC engines from the late 50’s through the 80’s. This cam has more lift and duration than even the 265 Power Pack cam. This grind is sold by several manufacturers at very reasonable prices. I hope this cam will make good power and still maintain a stock sounding idle in my 265. Lift I (.390) E (.410) Duration @.050 I (195) E(202) LSA 112º What do you think?
